As a web developer we need to debug our code in web browser. Those days are gone when developers use numerous numbers of alert to debug code. Though Visual Studio has powerful tools to debug client side code, often you need to debug code in web browser. Also remember not all web developers working with Visual Studio. Every web browser has a set of developer tools integrated with them. We all know about FireBug project. FireFox and Google Crome has good developer tools which can be very helpful at the time of coding and debugging. IE had a little old developer tools with version 10. Now Microsoft decided to update their web browser developer tools with some new touch to remain in the web browser competition.
